The <info>update</info> command reads the composer.json file from the
current directory, processes it, and updates, removes or installs all the
dependencies.

<info>php composer.phar update</info>

To limit the update operation to a few packages, you can list the package(s)
you want to update as such:

<info>php composer.phar update vendor/package1 foo/mypackage [...]</info>

You may also use an asterisk (*) pattern to limit the update operation to package(s)
from a specific vendor:

<info>php composer.phar update vendor/package1 foo/* [...]</info>

To run an update with more restrictive constraints you can use:

<info>php composer.phar update --with vendor/package:1.0.*</info>

To run a partial update with more restrictive constraints you can use the shorthand:

<info>php composer.phar update vendor/package:1.0.*</info>

To select packages names interactively with auto-completion use <info>-i</info>.
